A display device includes a display panel. A flexible printed circuit board is electrically connected to the display panel. A first pad is disposed on the display panel. A second pad is disposed on the flexible printed circuit board and overlaps the first pad. A first anisotropic conductive film is disposed between the first pad and the second pad. The first anisotropic conductive film is configured to bond the first pad to the second pad. The first anisotropic conductive film includes a conductive polymer. The first anisotropic conductive film includes at least one first conductive region that electrically connects the first pad and the second pad and at least one first insulating region.
